I'm a private individual interested in buying a custom top-of-the-line Mac Pro, mostly as a toy since I'm blessed enough to be able to afford it. The machine I'm interested in would be 3.2GHz Quad-Core Intel Xeon, 32GB, four 300GB SAS drives, NVIDIAQuadro FX 5600, and a couple Cinema HD Displays. With accessories, it runs about $23,397. I recently talked with an apple representative who actually tried to convince me to acquire a somewhat lower-end "suggested configuration" Mac Pro. He told me that the technical upkeep for such a high-end mac is more demanding than I could handle. Is this accurate? He also told me that he wasn't aware of any use a private individual could have for that amount of processing power, but I enjoy knowing the power is available, so this doesn't concern me. The only high-end software I run is some naval architecture CAD programs (Maxsurf, ShipConstructor and Navisworks) -- I'm a ship-building hobbyist. These programs would run in Windows under bootcamp. I would also use the machine for mostly mundane tasks -- internet, email, record-keeping, and my large music library. Any thoughts about the upkeep of this machine would be greatly appreciated. Is it possible for me to maintain this machine myself, with good computer proficiency, but no special skills?
